T0 all wh0m z't mag concern:

Be it known that; I, FRANCIS A. \VALSH, of Milwan'kee, in the connty of Milwaukee, and in the State of WViseonsin, have invented 0ertain new and useful Improvements in Die- Seaming Maohines; and I do hereby declare that the following is a full, elear, and exact desoription thereof.

My invention relates to die-seaming maohines, being a division of my applieation, N0. 308,317, filed April 23,1889; and it consists in oertain peouliarities of eonshuetion and combination of parts, to be hereinafter desoribed with referenee so the aeoompanying d rawings, anal subsequently claimed. In the drawings, Figure 1 represents a side elevation of my maehine, partly in seotion; Fig. 2,a horizontal seotion of a portion of Ehe maohine; and Fig'. 3,a f10ntelevation, partly in seet1ion.

Referring by letter to the drawings,A rep resents the base, and B B wo standards that The standards a1e provided vvith adj ustable gnides C for a slido D,the latter being oonneeted by an adjustable hanger E wih a erank-shaft F,

'that has its bearings in said standards.

Jonrnaled to the slide D is a cylindrical plunger G, having an impaet surfaee 01 anvil H (the latter being preferably removable) ancl diesI J upon its periphery. Fast on one end of the plunger is an arm K, that is provided With a lugbfor engagement With a slot c in t-he inner end. of the bar L, this bar being arranged in a guide d upon the rnaohineframe, and provided ab its outer end With a Ing e, that engages with a slot f in a lever M, pivotally conneoted to an ear g of said machine-frame, as besl: illustrated in Fig. l.

The slot c in t-he bar L is parallel to the 1novement of the slide D, and (hat end of the lever M fa1thest from said bar is provided with a projeetion h, (shown in dotted lines, Figs. 1 am]. 3,) tl1af; engages a oam-groovo in the hub i of a gear-wheel N, the latter being revolved upon a studj on the maohine-frame. The gear-wheel meshes With a pinion 0 011 the orank-shaft F, and is so timed as to make one revolution while said crank-shaft is mak ing two. The oam-groove in oho hubz' of said gear-wheel is formed with a planem on eaoh side of ifs axis, the two planes being joined by inolines n, so timed t-ha-t ab eaeh downward stroke of Ehe erank-shaft F one of the planes will bear upon tl1e projeotion h on the lever M, and ab eaoh upward stroke of said crankshaft one of bhe inolines will bear upon said projection, the purpose of tliis operation being hereinafter deseribed.

Seoured to the base A of the 1naehine below the plunger G is a horn P, provided With dies Q R in register With the dies I.Ion said plunger, and the horn may be also provided with gage-pins 19, as shown in Figs. 1 and 3.

In the operation of the maohine the Ing b 011 oho arm K Will inove in Ehe slot c in the bar L, while the slide D moves down to engage the dies I J on the plnnger G with the dies Q R in the horn I, theprojection h on the lever M being in one of Ehe planes m of the cam-groove in Ehe hub iof tl1e gearwheel N until said male and female dies are disengaged by tl1e upward movementof said slide. At this time one of tl1e inolines n of the camgroove bears against the projeetion on lever M and the lat-ter is moved on its pivot to aetuate the sliding bar L, whereby motion is eommunioated t0 alle arm K toroek the plungen G and bringthe an vil Hinto register With the plain portion of the horn P between the dies. The next downward movement of the slide im paefs the anvil against the horn,and while the return movement of said slide is taking plaoe the plnnger G is rookeol back to its normal position by means of ohe namand-lever mechanism above deseribed. The male and female dies are shaped to flange the opposingedges of asheet-metal blank,and these flanged edges being interlocked by tl1e operator of the machine they will be laid Clown by the aotion of the anvil I-I 130 complete a seam.

It may be found dosirable at times to nse the maohine for only one olass 0f the work above deseribed, and therefor6 I have proyided the slide D with a set-serew S for locking the plunger G against rotation, it being understood that when said plunger is thus locked ehe lever meehanisrn conneeting it with the cam-groove in the gear-wheel hub z is disoonnected.

I may find it desirable to place the a1wilH.

on the hor'n P and connect the latter witl1 the cam-actuated lever inechanisnn above deseribed, this constrnction beingshown by dotted lines in Fig. l. \Vl1en the n1achine is thus organized, the plunger is stationary in a rotary direction, and the rotary movementi above described in connection with said planger is transferred t0 the l10rn, the resnlt being"the same in either ease, it being understood (hat in this organization 0f said machine the dies are praetieally in the reverse 0t' what is show'n in the drawings.

Having Lhns deseribed my invention, what I claim as new, and desire 130 seeure by Letters Patent, is

1. In a die-seaming n1achi ne, a reciprocating rotary adj nstable plunger provided With dies, and a horn provided With dies eorresponding t0 those 011 the plunger, subsiant-ially as sei: fort-h.

2. In a die-seaming macl1ine, areeiproeating rotary adj ustable plunger provided with dies, suitable means for loeking the plunger in its adjusted position, and a l10rn provided Wllll dies corresponding t0 those 0n said plunger, substantially as set forth.

3. In a die-searning maehine, areciprocating slide, a plunger jonrnaled i0 the slide, dies 011 the plunger, a lever meehanism for imparting a rotary adjust-ment to the plunger, an d a l1orn provided witl1 dies corresponding to those 011 said plnnger, substantially as set fortl1.

4:. Inadie-seamingmachine,areeiprocating slide, a plnnger jonrnaled to the slid e, dies and arms 0n the plunger, a sliding bar provided with a sl0t parallel t0 the movement 0f said slide, a lug onthe plnnger-arm arranged t0 engage said slot, a pivoted lever eonnected t0 the sliding bar, a cam arranged t0 aetuate the lever, and a horn provided wirh dies corresponding t0 those 0n said plunger, substantially as deseribed.

5. In a die-seaming machine, a crank-shaft provided Witli a pinion, a slide eenneeted t0 the erank-shaft, a plnnger journaled so the slide, dies 011 the plnnger, a gear-wheel arran ged 110 1nesh with the erankshaft pinion, a eamand-lever mechanisrn conneeing the gear-wheel and plunger, and a horn provided wibl1 dies eorresponding t0 those on said plnnger, snbstantially as sei: forth.

6. In a die-seaming rnaehine, a iotary adjustable device provided With a pair of approximately parallel folding dies, anoher pair of folding-dies in direet opposition t0 those on the rotary adjustable deviee, and snitable m eehanisnn for reciprocating one pair 0f said dies, whereby two edges 0f a sheet- 1netal blank may be separately folded a1: one operation of the machine, substantially as sei: forth.

7. In a die-seaming machine, a rotary ad juscable deviee carrying an anvil and dies, a stationary surfaee for the impaet 0f the anvil, and dies in the stationary snrfa0e corresponding t0 those 0n said rotary adjnstable device, snbstantially as sei; f0rth.

8. In a die-seaming xnaehine, a drive-shaft, a plunger provided witl1 dies, a stationary surface provided With dies in opposition to those 0n the plunger, and a tirned mechanism c0nneeting the sl1aft and plnnger to shift the latter ab each rotation of said sl1aft, and tl1ereby bring the dies 0n said plunger in and 0ut 0f their working position, snbstantially as set fortl1.

9, In a die-seaming maehine, apairof single edgefolding dies, a seam-elosing surfaee on a line parallel t0 the dies, another pair 0f Single edge-folding dies and a seamclosing surfaee in direct opposition t0 the dies and sean1- closing snrfaee first n'amed, and suitable 1neehanism f0r reeiproeating one sei; 0f dies and a seam-elosing surfaee, wh ereby two edges 0f a sl1eetxnetal blank 1nay be separately folded a one operation 0f the machine and the seam formed bya subsequent union of the folds elosed l y a seeond operation of said maehine, substantially as sei; forth.

In testimony thatI claim the foregoing I have hereunto Set my band, at Milwaukee, in the connty 0f Milwankee and State 0f \Visconsin, in the presence of two witnesses.
